So yesterday me and my boyfriend had sex, we used a condom and I am on the pill and always take it correctly, when he withdrew we noticed a frothy, white runny liquid on the outside of the condom, there was no evidence of a leak or hole, and his ejaculate was still held in the end of the condom, what could this be? Is there a big chance of pregnancy? I'm on day 3 of my pill break and no period, so feeling very worried.
